    In the latest version of 
    livekit_client: 2.2.3
    and 
    flutter_webrtc: ^0.11.6
    it is not possible to switch audio device on Android using 
    room.setAudioOutputDevice(device)
    . It seems like its the OS who decide what audio device to use since I can't switch from either speakerphone (if no bluetooth headset is connected) or bluetooth headset.

    Sorry, here is the code Future<void> _connectToRoom() async { try { _room = Room(); await _room!.connect(url, token); // _listener = _room!.createListener(); //await _room!.participant.listen(_onTrackSubscribed); // _room!.onParticipantConnected.listen(_onParticipantConnected); // _room!.onParticipantDisconnected.listen(_onParticipantDisconnected); } catch (error) { print('Failed to connect to room: $error'); } } // void _onParticipantConnected(ParticipantConnectedEvent event) { // event.participant.onTrackSubscribed.listen(_onTrackSubscribed); // event.participant.onTrackUnsubscribed.listen(_onTrackUnsubscribed); // } // void _onParticipantDisconnected(ParticipantDisconnectedEvent event) { // // Handle participant disconnect if needed // } void _onTrackSubscribed(TrackSubscribedEvent event) { if (event.track is VideoTrack) { setState(() { _videoTracks.add(event.track as VideoTrack); }); } } void _onTrackUnsubscribed(TrackUnsubscribedEvent event) { if (event.track is VideoTrack) { setState(() { _videoTracks.remove(event.track as VideoTrack); }); } } @override Widget build(BuildContext context) { return Container( width: widget.width, height: widget.height, child: _videoTracks.isNotEmpty ?

    Hi team! I set up the new VoiceAssistant (amazing work) on a python backend similar to the example you published on GitHub. I am now trying to render in Next.js the chat message history similar to how it is rendered on the LiveKit cloud playground (i.e. streamed transcription of user message & voice assistant reply). I tried wrapping the 
    <Chat/>
    component within 
    <LiveKitRoom/>
    after wrapping it in`<LayoutContextProvider/>`(throws LayoutContext error otherwise), as well as through useChat():
    Copy code
    const { chatMessages: messages, send } = useChat();
  console.log(messages)
    However, in both cases I can't get any messages returned although the voice assistant answers everything nicely on audio. Can you help point me in the right direction?

    When we run 
    client.deleteRoom(videoRoomUUID).execute();
    from our backend and mobile participants are currently connected to the room. Webhooks 
    room_finished
    AND THEN 
    room_started
    are trigger leaving us with a new and empty room every single time. When running web to web, we have no issue at all. We are using Flutter and 
    livekit-server 1.7.0
    server-sdk-kotlin 0.5.9

    Hi Team! I am wondering if there is a way to update tokens. If so where can I learn about it? For context: I am making a livekit demo where admin can create room and invite people and give them certain permissions. The generated token will then be: localhost:3000/room?permissionToken=....... The permission token is a token with only the permsions and room name. When a user goes to the link it generates a new token based on the permission token and adds identity of the user. If the admin kicks the user out nothing stops him from rejoining. I want to make the link with the permission token invalid. Is there a way to invalidate a token? Thank in advance for your time!

    I have tested the demo code that was present in docs, but i dont understand few things: 1. What really is LiveKit doing? Is it like a framework for Audio-Video, same as langchain is for LLMs? 2. I have noticed that it uses deepgram, is it really required? Doesn't LiveKit has it's own TTS and STT service? Isn't that what pricing is for? 3. I don't want to use rooms and all. Only api call and it should answer it. Is it possible? I find LiveKit interesting but i am unable to understand the pricing of it and use of deepgram and all.

    Hello, team! I've managed to integrate livekit sip with asterisk. It works I can connect the voip client (like Zoiper) to livekit room, but when I try mute/unmute on voip client seems the livekit sip participant doesn't catch this state changes. Is it bug? Or livekit sip doesn't support mute/unmute sip participants yet? Thanks

    Hi Team, We are following the documentation provided for the self-hosting egress service. I have a question about the websocket URL we are configuring for the livekit egress service. The WS URL we are passing in the client side(front-end) is the Livekit cloud URL and in our local self-hosting egress client, we are configuring the local WS URL. Is that the correct approach or does the WS URL need to be the same? We are trying to implement it with the LiveKit cloud but want to host the Egress Service locally.

    Hi Everyone, I’m currently working on extending the functionality of a DownTrack implementation in a WebRTC-based project. Context: In the existing codebase, the handleMute function for DownTrack is designed to handle muting and unmuting of media streams. For audio tracks, when a mute event is triggered, the code ensures that a few silence frames are sent to maintain the comfort noise generator in a stable state on the decoder side. This is achieved through the following code:
    Copy code
    if d.kind == webrtc.RTPCodecTypeAudio && muted {
    d.writeBlankFrameRTP(RTPBlankFramesMuteSeconds, d.blankFramesGeneration.Load())
}
    This works perfectly for audio, ensuring that when the audio stream resumes, there is no undesirable noise. The Problem: I have extended this functionality to the video stream by attempting to implement a similar approach. My expectation was that the video stream would resume normally after unmuting, just as the audio stream does. However, in practice, the video stream gets stuck and does not resume as intended.

    Hi, team, I am very thankful to all the wonderful things you guys have done for the community, and I am reaching the final phase of releasing my app built upon livekit. As I am a new developer and it’s the first time for me to use open source resources to build something, I am worried that I don’t know enough about how to properly declare the copyright of livekit, can anyone tell me what are the musts, or are there any formats that I can follow to ensure I follow all the necessary conventions?

    Hey there! I am wondering if LiveKit is now fully supported on Unity for Meta Quest (Android)? I saw that version 1.0.0 of the Unity SDK now supports all native platforms but I am wondering if all LiveKit features are now 100% supported for Android/Quest? And are there any known issues?
